The other day I cleaned my carpets and I went to turn on just the blower motor "on" to keep air moving in the house.It comes on for approximately 20-30 seconds then seems to go into a fault mode. The heat cycle seems to be working fine. The sequencing does what it is supposed to flames come on for about two minutes then shuts down but the blower continues to run then the fire restarts. I switched the motor leads at the board to see if the heat cycle would run in the fatser speed but the blower faulted after about 20-30 seconds again. DO you think I have a motor that is not working up to par?? It seems the board is doing what it is supposed.

Thanks,
Jim

What you need to find out is whether you losing voltage to the motor or not. If you are, you will need to look at what is suppling the power to it. If you are not losing power to the motor, It could be a bad capacitor or the motor could be dropping out on overload. Overload is normally caused from the motor drawing too many amps and overheating.

If in doubt call a pro !
